Abstract
Energy consumption has increased considerably in the last years. How to reduce and make energy consumption more efficient in home environments has become of great interest for researchers. This could be achieved by introducing a Home Energy Management System (HEMS) into user residences. This system might allow the user to control the devices in the home network through an interface and apply energy management strategies to reduce and optimize their consumption. Furthermore, the number of devices and appliances found in users residences is increasing and these devices are usually manufactured by different producers and can use different communication technologies. This paper tackles this problem. A home gateway which integrates different devices with a HEMS based on set of semantic-web tools providing a common control interface and energy management strategies.
